The black squirrel monkey[1], also called the black-headed squirrel monkey or the blackish squirrel monkey is a small New-World monkey native to the central Amazonian region of Brazil.
- Black squirrel monkeys are primates with dark eyes surrounded by a round mask of white fur.
- The short, dense fur on its back is black-grey, while its underbelly, forearms, and limbs are yellowish.
- Its ears and neck are white, and the skin around its nostrils and lips is hairless and black.
- The black hair above the eyes forms a flat arch and sits lower on the forehead than in other squirrel monkey species. This is one of the main distinguishing features that set them apart from other species of squirrel monkeys.
- In addition, its long, slender tails, narrower than those of other squirrel monkey species, are used for balance when climbing branches and are twice their body length.
- The tip of the tail is dark in color and much bushier than the rest.
